Description: Generally speaking, the low melting point polyester chip refers to one specialty polymer with a melting point between 90℃ and 220℃. The melting point of polyester is the temperature at which a solid crystalline substance changes from a solid state to a liquid. So it reflects the purity of polyester. Generally speaking, pure polyester is a partially crystalline polymer with a melting point of 265℃. But during actual production, some impurities exist in the polyester due to various side reactions. At the same time, the defects of polymer crystals and the difference in crystallinity will also affect the melting point. The common type of low melt polymer is 110℃. But we can also offer a melting point of 90℃, 120℃, 160℃, and 180℃.
